Message Processing for Cloud Computing Applications

1. A non-transitory machine-readable medium storing a program executable by at least one processing unit of a device, the program comprising sets of instructions for: receiving, from a user of a client device, a message comprising a particular sequence of characters; determining a language from a plurality of languages associated with the message based on the particular sequence of characters of the message; determining a model from a plurality of models that corresponds to the determined language; determining a function from a plurality of functions provided by a computing device that is associated with the message by providing the particular sequence of characters as input to the determined model and using a function output by the determined model as the determined function; and sending the computing device a request to perform the function.

2. The non-transitory machine-readable medium of claim 1 , wherein the message is a first message, wherein the program further comprises sets of instructions for: receiving a response to the request from the computing device; and sending the client device a second message that includes the response.

3. The non-transitory machine-readable medium of claim 1 , wherein the computing device comprises an application, wherein the plurality of functions is provided by the application.

4. The non-transitory machine-readable medium of claim 1 , wherein each model in the plurality of models comprises a set of mappings, each mapping in the set of mappings specifying a function and a sequence of characters, wherein determining the function from the plurality of functions comprises: determining a mapping in the set of mappings of the model that specifies a sequence of characters that matches the particular sequence of characters of the message; and identifying the function specified in the mapping as the determined function.

5. The non-transitory machine-readable medium of claim 4 , wherein determining the function from the plurality of functions further comprises: removing punctuation from the particular sequence of characters of the message; and converting the particular sequence of characters of the message to lowercase characters.

6. The non-transitory machine-readable medium of claim 1 , wherein determining the function from the plurality of functions further comprises sending a natural language processing system a request to determine the function from the plurality of functions.

7. The non-transitory machine-readable medium of claim 1 , wherein the message further includes one or more graphical symbols.

8. A method comprising: receiving, from a user of a client device, a message comprising a particular sequence of characters; determining a language from a plurality of languages associated with the message based on the particular sequence of characters of the message; determining a model from a plurality of models that corresponds to the determined language; determining a function from a plurality of functions provided by a computing device that is associated with the message by providing the particular sequence of characters as input to the determined model and using a function output by the determined model as the determined function; and sending the computing device a request to perform the function.

9. The method of claim 8 , wherein the message is a first message, wherein the method further comprises: receiving a response to the request from the computing device; and sending the client device a second message that includes the response.

10. The method of claim 8 , wherein the computing device comprises an application, wherein the plurality of functions is provided by the application.

11. The method of claim 8 , wherein each model in the plurality of models comprises a set of mappings, each mapping in the set of mappings specifying a function and a sequence of characters, wherein determining the function from the plurality of functions comprises: determining a mapping in the set of mappings of the model that specifies a sequence of characters that matches the particular sequence of characters of the message; and identifying the function specified in the mapping as the determined function.

12. The method of claim 11 , wherein determining the function from the plurality of functions further comprises: removing punctuation from the particular sequence of characters of the message; and converting the particular sequence of characters of the message to lowercase characters.

13. The method of claim 8 , wherein determining the function from the plurality of functions further comprises sending a natural language processing system a request to determine the function from the plurality of functions.

14. The method of claim 8 , wherein the message further includes one or more graphical symbols.

15. A system comprising: a set of processing units; and a non-transitory machine-readable medium storing instructions that when executed by at least one processing unit in the set of processing units cause the at least one processing unit to: receive, from a user of a client device, a message comprising a particular sequence of characters; determine a language from a plurality of languages associated with the message based on the particular sequence of characters of the message; determine a model from a plurality of models that corresponds to the determined language; determine a function from a plurality of functions provided by a computing device that is associated with the message by providing the particular sequence of characters as input to the determined model and using a function output by the determined model as the determined function; and send the computing device a request to perform the function.

16. The system of claim 15 , wherein the message is a first message, wherein the instructions further cause the at least one processing unit to: receive a response to the request from the computing device; and send the client device a second message that includes the response.

17. The system of claim 15 , wherein the computing device comprises an application, wherein the plurality of functions is provided by the application.

18. The system of claim 15 , wherein each model in the plurality of models comprises a set of mappings, each mapping in the set of mappings specifying a function and a sequence of characters, wherein determining the function from the plurality of functions comprises: determining a mapping in the set of mappings of the model that specifies a sequence of characters that matches the particular sequence of characters of the message; and identifying the function specified in the mapping as the determined function.

19. The system of claim 18 , wherein determining the function from the plurality of functions further comprises: removing punctuation from the particular sequence of characters of the message; and converting the particular sequence of characters of the message to lowercase characters.

20. The system of claim 15 , wherein determining the function from the plurality of functions further comprises sending a natural language processing system a request to determine the function from the plurality of functions.
